Gene expression is central to the genotype-phenotype relationship in all organisms, and it is
an important component of the genetic basis for evolutionary change in diverse aspects of …

The connection between development and evolution has become the focus of an increasing
amount of research in recent years, and heterochrony has long been a key concept in this …

The Dynamic Energy Budget theory unifies the commonalties between organisms, as
prescribed by the implications of energetics, and links different levels of biological …

Living things are unimaginably complex, yet they have withstood a withering assault of
harmful influences over several billion years. These influences include cataclysmic changes …

An argument is proposed to explain the origin of large metazoans, based on the regulatory
processes that underlie the morphogenetic organization of pattern in modern animals …

This chapter examines the origin and diversification of metazoan larvae and developmental
modes. It discusses the major features of larval evolution, and considers their developmental …

The switch from feeding to nonfeeding larvae is an ecologically important transformation that
has evolved on several separate occasions within the echinoids. In each case, this life …

Many life‐history and developmental studies of marine invertebrates assume that eggs of
species with nonfeeding larvae are large because they provide materials for rapid …

In the maximal form of indirect development found in many taxa of marine invertebrates,
embryonic cell lineages of fixed fate and limited division capacity give rise to the larval …

The 'origin of larvae'has been widely discussed over the years, almost invariably with the
tacit understanding that larvae are secondary specializations of early stages in a …
